Texas Instruments PINA4180A1PW

The INA180, INA2180, and INA4180 (INAx180) current sense amplifiers are designed for
cost-optimized applications. These devices are part of a family of current-sense amplifiers (also
called current-shunt monitors) that sense voltage drops across current-sense resistors at
common-mode voltages from –0.2 V to +26 V, independent of the supply voltage. The INAx180 integrate
a matched resistor gain network in four, fixed-gain device options: 20 V/V, 50 V/V, 100 V/V, or 200
V/V. This matched gain resistor network minimizes gain error and reduces the temperature
drift.

All these devices operate from a single 2.7-V to 5.5-V power supply. The single-channel
INA180 draws a maximum supply current of 260 µA; whereas, the dual-channel INA2180 draws a maximum
supply current of 500 µA, and the quad channel draws a maximum supply current of 900 µA..

The INA180 is available in a 5-pin, SOT-23 package with two different pin configurations.
The INA2180 is available in an 8-pin VSSOP package. The INA4180 is available in a 14-pin TSSOP
package. All device options are specified over the extended operating temperature range of –40°C to
+125°C.
